I have strong feelings when it comes to marinade and sauce. Adding a simple sauce is a delicious, easy way to perk up dinner, no matter what’s on the plate. And 20 minutes in a marinade can infuse a cut of meat, poultry, or fish with deeper flavor, not to mention add moisture. These 21 favorites are the ones I keep on constant rotation in my meal plan, both because they’re packed with flavor and because they make an ideal finishing touch.
